Find out the capacitance of a parallel plate capacitor in air. What is the effect of distance between the plates of’ the capacitors on its capacitance?

A parallel plate capacitor is to be designed, using a dielectric of dielectric constant 5, so as to have a dielectric strength of 10^(9)V*m^(-1) . If the voltage rating of the capacitor is 12kV, the minimum area of each plate required to have a capacitance of 80pF is

Half of the space between the plates of a parallel-plate capacitor is filled with a dielectric material of dielectric constant K. The remaining halt contains air as shown in the figure. The capacitor is now given a charge Q. Then

A parallel plate capacitor of capacitance 90 pF is connected to a battery of emf 20V. If a dielectric material of dielectric constant k=(5)/(3) is inserted between the plates, the magnitude of the induced charge will be

A few capacitors are joined in parallel. Find the equivalent capacitance of the combination.

Statement I: If the distance between the parallel plates of a capacitor is halved and dielectric constant is made three times the capacitance becomes 6 times. Statement II: Capacitance of the capacitor does not depend on the nature of the material of the plates of the capacitor.

A parallel-plate capacitor of area A, plate separation d and capacitance C is filled with four dielectric materials having dielectric constants k_1,k_2,k_3 and k_4 as shown in the figure below. If a single dielectric material is to be used to have the same capacitance C in this capacitor, then its dielectric constant k is given by
